400 Series Squadrons
Welcome to the archive of Canada's 400 series flying squadrons. This
system of numbering was a product of the Second World War; to avoid confusion
among Commonwealth units flying in England, all Allied units were renumbered,
and the Royal Canadian Air Force (RCAF) received the 400-449 block of
numbers. 450 Squadron was created in 1968; although the Royal Australian
Air Force already had a 450 Squadron (a tactical fighter squadron during
the Second World War), the duplication of numbers was not realised until
after the Canadian squadron was formed. There are no formal links between
the two squadrons.
Since the 400 series numbering was implemented when Canada's air force
was known as the RCAF, we have chosen to display most of the badges in
their original form, with either the King's or Queen's crown. The badges
were changed between 1968 and 1970 when the RCAF was disbanded and replaced
by the Canadian Armed Forces (CAF). The names listed below are the last
known titles for each squadron.
